I'm shocked. I fly this route 3-4 times a year and have never seen a trans-con "level" of F service. In fact, I stopped wasting my stickers on it because its a 4 sticker trip, and I got tired of getting a pizza and nuts.
If AA has "upgraded" this flight to trans-con status, I'll upgrade anytime. Its a 4 hour flight and there's no reason to NOT give up the full monty.
